386 A. M. Edwards — Deposit of Diato??iacece. 



Newark meadows, X. J., where I have collected the Champlain 



(?) deposits, I will mention the following as typical, and from 

 which I have gathered the clay, blue, gray or white, and made 

 slides : Harrison, near the bridge ; opposite Athar's factory ; 

 opposite Lister's factory ; by Hillings worth's factory ; between 

 Hillingsworth's factory and the P. R. It. bridge ; Frank Creek, 

 half way across the meadows ; near the P. R. R. No. 1 and 

 No. 2 ; near the bridge over the Passaic River ; on the exten- 

 sion of the P. R. R. ; raised meadows on the P. R. R. ; Wood- 

 ruff's Creek, near Elizabeth ; near Linden Park No. 1 and No. 

 2, Elizabeth ; back of Jersey City ; in Jersey City, at the third, 

 street from New York Bay ; Elizabethport ; Bay Way, Eliza- 

 bet] iport; Kingsland ; Sewarren ; Kearney; Peddie Street 

 Ditch; Signal post on the L. Y. R. R.,. Bound Creek; and 

 Arrowchar, S. I., N. Y. Besides these I have the same clay 

 from near New Haven, collected by myself, and also sent to 

 me by Mr. W. A. Terry, of Bristol, Conn. ; near Boston, Mass., 

 from Mr. F. F. Forbes and Mrs. S. A. Fuller ; also from Mr. 

 L. Woolman, as clay, water works, Absecon, N. J. ; Bingham 

 House, No. 1 and 2, Philadelphia, Penn. ; 11th and Market 

 streets, Philadelphia ; Spreckel's Refinery, Reed Street Wharf, 

 Philadelphia; abutment Walnut Street Bridge, Philadelphia; 

 Gray's Ferry, B. & O. R. R , and he records in the Microscop- 

 ical Bulletin for October, 1892, " Fossil Diatoms in Philadel- 

 phia beneath the girls' new Normal School buildings." And 

 I am also indebted to Mr. C. L. Peticolas for a slide from 

 Cornfield Point, St. Mary Co., Md. I have also to record that 

 Professor J. W. Bailey discovered in the earth of the rice 

 fields at Savannah, Ga., DiatomaceEe. This I received at the 

 same time, about forty years ago, from Dr. W. C. Daniels, 

 Savannah, Ga. Bailey records it in his Microscopical Observa- 

 tions made in South Carolina, Georgia and Florida, and pub- 

 lished in 1850 in the Smithsonian Contributions to Knowledge, 

 Yol. II, page 5. Dr. F. W. Lewis records the finding of 

 Diatomacese in the blue clay of the Delaware River, Philadel- 

 phia, Penn., in his Notes on new and rarer species of Diato- 

 macese of the United States seaboard, 1861. 



We now come to mention the species of Diatomacese found 

 in the Champlain (?) deposits of the Littoral Plain. They 

 include the following : 



Achnaxthes hirta, O. F. M., lanceolata, A. de B. 

 Actinocyclus ternarius, C G. E. 

 Aotinopttchus biternarius, C. G. E. 



Amphiprora alata, C. G. E., lepidoptera, W. G., pulchra, J. W. B. 

 Amphora cymbifera, W. S., lanceolata, P. T. C, pellucida, 

 W. G., robusta, W. G., undata, H. L. S. 

 Amphitetras antediluviana, C. G. E. 

 Brebissoxia lanceolata, C. A. A.
